The controller acts as a main peripheral device on the Maple Bus.
Controller
The "get condition" command (0x09) with controller function code is used to poll controller state. A "data transfer" command (0x08) is returned with controller function code word plus 2 words of data. The returned data must be parsed differently depending on the function definition for the controller. The below sections show how to parse data for a standard controller.
First Data Transfer Word
All button bits are 0 when pressed and 1 when released.
| Byte 0 (LSB) | Byte 1 | Byte 2 | Byte 3 (MSB) |
|---|---|---|---|
| Left analog trigger 0 to 255 0: fully released 255: fully pressed |
Right analog trigger 0 to 255 0: fully released 255: fully pressed |
Button bits 0x01: Z 0x02: Y 0x04: X 0x08: D 0x10: Up-b 0x20: down-b 0x40: left-b 0x80: right-b |
Button bits 0x01: C 0x02: B 0x04: A 0x08: Start 0x10: Up 0x20: Down 0x40: Left 0x80: Right |
Second Data Transfer Word
| Byte 0 (LSB) | Byte 1 | Byte 2 | Byte 3 (MSB) |
|---|---|---|---|
| Right analog stick up/down 0: fully up 128: center 255: fully down |
Right analog stick left/right 0: fully left 128: center 255: fully right |
Left analog up/down 0: fully up 128: center 255: fully down |
Left analog left/right 0: fully left 128: center 255: fully right |
